Ancient, or broken, pot? (9)
I believe the answer is:
container
'pot?' is the definition.
(pot is a kind of container)
'ancient or broken' is the wordplay.
'broken' is an anagram indicator.
'ancient'+'or'='ancientor'
'ancientor' anagrammed gives 'CONTAINER'.
(Other definitions for container that I've seen before include "Large box for commercial transportation" , "Something to hold" , "Metal box for carrying goods by ship" , "It holds things" , "Receptacle" .)
